SPECIFICATION forming part of Letters Patent No. 658,093, dated se tember 18, 1906. Application filed July 24:, 1899. Serial No. 724,935. KNO odel- To all whom, it may col Learn:

Be it known that I, ELTON W. MCOASLIN, a

citizen of the United States, residing at Chimit the rim thus converted to be readilychanged back to a rim of the clincher typethat is to say, a rim adapted for Whatis known as a .clincher-tire.

To the attainment of the foregoing and other useful ends my invention consists in matters hereinafter set forth.

In the accompanying drawings, Figure 1 represents in perspective a portion of a wheelrim primarily of the clincher type converted into a crescent rim. Fig. 2 shows in perspective a portion of the converting-strip em- 2 5 ployed in Fig. 1 on a slightly-larger scale.

Fig.3 is a section taken longitudinally through a portion of the wheel-rim along the middle line thereof. Fig. 4 is a view similar to Fig.

1,showing a slightly-modified form of clincher- 0 rim converted into a crescent rim. Fig. 5 is a like view showing another form of clincherrim converted into a crescent rim.

In Figs. 1 and 3, A indicates a wooden rim of the clincher typethat is to say, it has a 5 longitudinal middle channel a, longitudinal seats a, respectively, at opposite sides of the middle channel, and side walls M, which rise from the outer edges of the seats a, it being understood that in the completed wheel-rim the channel a, the seats ct, and the walls a are all annular. The rim thus described may be said to come under the clincher type and is adapted When thus constructed to receive a tire having a longitudinally-divided casing 5 which is provided along its edges with wire rings adapted to bear upon the seats a when the tire is in place and in an inflated condition.

B represents a strip composed of rubber or 5o rubber composition, with or without a facing of cloth, it being preferable, however, to form the stripof any suitable rubber composition and to provide it with face-strips b b of fabric. This strip, which I term a converting-strip,

'is adapted on one side to fit the groove or channel a, the seats a, and the side walls a of the wheel-rim, the opposite side of said strip being transversely concave, so that when the strip is applied to the rim A, as illustrated in Fig. 1, the rim will be converted into a crescent rim adapted to provide a seat for an annular tubular pneumatic tire of the Morgan & Wright type. The con vertingstrip B can be made of such length that when applied to the wheel-rim its ends will meet v and abut. The converting-strip can be cemented to the wheel-rim along its entire length and at different points, and it can be further secured upon the rim by a strip 0 of fabric laid over the abutting ends of the converting-strip and cemented to the latter, as in Fig. 3, it also being observed that, if desired, the strip 0 can be made to provide the sole means for securing the converting-strip to the wheel-rim. 7 5

When desired, the user can remove the con- Vert-ing-strip by first tearing oh. the strip 0 and then tearing the converting-strip from the wheel-rim if the converting-strip is cemented thereto.

In Fig. 4 the Wheel-rim D is understood to be made of metal and is so formed to provide a middle channel (1, upwardly-diverging side 'walls 01, and curled edges d for substantially the purposes of the construction of wheelrim shown in Fig. 1.

In Fig. 4 the converting-strip B is similar to the strip shown in Figs. 1 and 2, with the exception that as a matter of form it has one of its sides adapted to the particular formation of the wheel-rim D, its opposite sides, however, being concave in cross-section, so that when the strip is applied it will convert the wheel-rim into a crescent rim.

In Fig. 5 the wheel-rim E is an ordinary 5 wood rim. It is formed with a central chan- 2 esspee ceding figures, whileits opposite side is'adapted to fit the tread side of the wheelrim involving the channels 6 e and the hook-shaped side Walls 6 The wheel-rim E is primarily adapted for a clincher-tire divided along its base, which latter is molded to fit the grooves e e; but

when the strip B is applied, as shown, the rim E is converted into acrescent rim adapted for a tubular tire of the Morgan 65 Wright type or for a single-tube tire.

By the foregoing arrangement the user of a bicycle or like'velocipede can start out with clincher-tires and yet at any time substitute annular tubular tires either of the Morgan & Wright type or of the hose-pipe or single-tube type, it being obvious that it will only be necessary to first apply to the wheel-rim the converting-strip B, which will convert the clincherrim into a crescent rim. These strips can be made quite cheaply and economically and can be furnished riders of wheels at a very small cost.

Where riders happen to have wheels with rims for clincher-tires and desire to use single or double tube tires of the clincher type, it will not be necessary for them to purchase new wheels, since by using the convertingstrip 13 the Wheel-rims can be'readily converted into crescent-rims.

A further advantage is that although the wheel-rim may have thus been converted in to a crescent rim it can at any time be converted back into a rim for aclincher-tire, and hence should the rider at any time find it necessary to immediately provide a new tire and should find it more convenient, owing to locality, to get hold of a clincher-tire he can readily use the clincher-tire by removing the convertingstrip B. a

What I claim as my invention isl. The combination with a bicycle or other velocipede wheel-rim of the clincher type, of a converting-strip applied and fitted to such rim and converting the same into a crescent rim adapted for a tubular tire such as set forth.

2. A clincher-tire Wheel-rim provided with a converting-strip, such as set forth, applied to the periphery of the wheel-rim with its ends abutting or in juxtaposition, and a fasteningstrip 0 applied over said ends of the strip. ELTON W. MOOASLIN. Witnesses:
